“However, Neigh Bridge lake is very deep, with layers of very cold water and thick blankets of weed; all of which are a recipe for disaster for even the strongest swimmers. There are plenty of signs asking to refrain from swimming, so please do not ignore them.

“Similarly, we do also ask that dogs are kept away from the water. Aside from the disturbance to wildlife and anglers, there are blooms of potentially toxic blue-green algae every year.

Blue Green Algae naturally occurs in inland waters, estuaries and the sea. Blooms can form when their numbers become excessive.

Once algal numbers are high, the bloom is likely to persist throughout the season, declining only on the onset of winter conditions.

Jim Ratcliffe, from the Environment Agency, said: “As always, if people see any environmental impacts due to dry weather, such as fish in distress, or Blue Green Algae, please report it to the Environment Agency incident line on 0800 80 70 60 open 24/7, so we can investigate and take appropriate action to protect people and the environment.”
